This sensor must be installed in compliance with the control panel system
installation manual. The installation must meet the requirements of the Au-
thority Having Jurisdiction (AHJ). Sensors offer maximum performance when
installed in compliance with the National Fire Protection Association (NFPA);
see NFPA 72.
Before installing sensors, please read the system wiring and installation man-
ual thoroughly. This manual provides detailed information on sensor spac-
ing, placement, zoning, and special applications. Copies of these manuals are
available from Notifier.

GENERAL DESCRIPTION

Model FST-951-SELFT is a field programmable intelligent sensors that uses a
state-of-the-art thermistor sensing circuit for fast response. These sensors are
designed to provide open area protection with 50-foot spacing capability as
approved by UL 521. The intelligent temperature sensor can be programmed
as either a 135°F fixed temperature sensor, a rate of rise and 135°F fixed tem-
perature sensor or a 190°F high temperature sensor through the Fire Alarm
Control Panel (FACP). Its internal Self-Test unit and beaconing capability can
test the detector to relevant requirements of NFPA 72.
Two LEDs on each sensor light to provide a local, visible sensor indication.
Remote LED annunciator capability is available as an optional accessory
(Part No. RA100Z). Rotary dial switches are provided for setting the sensor's
address. (See Figure 1.)

Notifier panels offer different feature sets across different models. As a result,
certain features of the Intelligent Programmable Temperature Sensors may be
available on some control panels, but not on others. FST-951-SELFT will sup-
port only FlashScan® protocol mode.
The possible features available if supported by the control panel include:
1. The sensor's LEDs can operate in three ways—on, off, and blinking–and
they can be set to red, green, or amber. This is controlled by the panel.
2. The remote output may be synchronized to the LED operation or con-
trolled independent of the LEDs. Please refer to the operation manual for
the UL listed control unit for specific operation of these models

3. Devices are point addressable up to 159 addresses.
4. The heat sensor operates as a programmable heat detector.
5. Yearly maintenance, in accordance to NFPA 72, can use the built in Self-
Test functionality.
Intelligent programmable temperature sensors require compatible addressable
communications to function properly. Connect these sensors to listed-compat-
ible control panels only.

WIRING GUIDE

All wiring must be installed in compliance with the National Electrical Code,
applicable local codes and the Authority Having Jurisdiction. Proper wire
gauges should be used. The installation wires should be color coded to limit
wiring mistakes and ease system troubleshooting. Improper connections will
prevent a system from responding properly in the event of a fire. Please note
that installation distances, wiring styles and wire gauge requirements may
vary for Self-Test sensors in comparison to standard sensors, please refer to
the panel's SLC Wiring documentation for further information.
Remove power from the communication line before installing sensors.
1. Wire the sensor base (supplied separately) as shown in the wiring
diagram. (See Figure 2.)
2. Set the desired address on the rotary dial switches. (See Figure 1.).
3. Install the sensor into the sensor base. Push the sensor into the base
while turning it clockwise to secure it in place.
4. After all sensors have been installed, apply power to the control unit and
activate the communication line.
5. Test the sensor(s) as described in the TESTING section of this manual.
